Help with a script please

I have limited knowledge in programming.

My goal is:

When playing on midi channel 1, remap channel 1 NoteOn, NoteOff and ControlChange to channel 1 to 4 simultaneously.

When playing on midi channel 5, remap channel 5 NoteOn, NoteOff and ControlChange to channel 5 to 8 simultaneously.

The first part works

The second doesn't.

Its the first time i'm using the ''while'' condition. I don't know how to set the midi channel range from 5 to 8

Thanks for any help!

var inst1 = 1;
var inst2 = 5

function HandleMIDI(event) {

  if (event instanceof NoteOn && event.channel == inst1||
  			event instanceof NoteOff && event.channel == inst1 ||
  			event instanceof ControlChange && event.channel == inst1)	{
    
      var i = 1;
      while (i <= 4) {
         event.channel = i;
         event.send();
         i++
         }
         }
         
   
     else if (event instanceof NoteOn && event.channel == inst2||
  			event instanceof NoteOff && event.channel == inst2 ||
  			event instanceof ControlChange && event.channel == inst2)	{
    
      var i = 1;
      while (i <= 8) {//here's where i'm stucked. Should be set to send on channels 5 to 8
         event.channel = i;
         event.send();
         i++}   
  
      
   }
   else {event.send()}




    event.send(); //Pass MIDI events through the plug-in.
}

I'm a coder, but not used the scripting in Logic yet, but looking from a code perspective you should be able to just set the starting channel (i.e. 5) so:-

      var i = 5;
      while (i <= 8) {....etc

You could also use a for loop to specify a range, but this should work providing event.channel/event.send is correct.  

For..loop would be something more like this:-

for (i = 5; i <= 8; i++) { 
         event.channel = i;
         event.send();
}
